ABSTRAK
Dengan perkembangan yang pesat dan pertumbuhan industri, pemanasan di seluruh dunia dan
penipisan sumber daya alam telah menjadi keprihatinan bagi masyarakat, kerajaan dan
industri. Dengan itu, topik hijau menjadi isu yang penting. Walaupun kerajaan negeri Pulau
Pinang telah berusaha untuk mempromosikan inisiatif hijau di Pulau Pinang, rantai bekalan
hijau belum dilaksanakan secara meluas oleh industri di Pulau Pinang terutamanya industri
kecil dan sederhana (IKS). Oleh kerana itu, kajian ini adalah untuk mengkaji halangan yang
menghalang IKS di Pulau Pinang daripada melaksanakan inisiatif rantai bekalan hijau. Selain
itu, kajian ini juga mengkaji kesan moderator orientasi perniagaan strategik dalam hubungan
antara halangan dan inisiatif hijau rantai bekalan. Untuk mencapai tujuannya, pendekatan kaji
selidik untuk industri berkenaan dilancarkan di kajian ini yang mana sampel daripada 92
responden IKS di Pulau Pinang telah dikumpul melalui kaedah kaji selidik. Analisis kaedah
SPSS telah digunakan untuk analisa deskriptif dan regresi. Keputusan analisis menunjukkan
bahawa pelaksanaan inisiatif hijau rantai bekalan oleh IKS di Pulau Pinang adalah rendah.
Salah satu pencapaian rendah daripada inisiatif hijau rantai bekalan (pembelian hijau)
mempunyai hubungan yang kuat antara halangan sumber daya, sikap dan halangan persepsi.
Halangan teknikal juga menjadi faktor yang menghalangkan pelaksanaan rekaan untuk
persekitaran oleh IKS di Pulau Pinang. Namun, kajian ini tidak dapat membukti dan
meyakinkan untuk menyokong kesan moderator orientasi perniagaan strategik dalam
hubungan antara halangan dan inisiatif rantai bekalan hijau. Dengan keputusan dan hasilan
yang didapati daripada kajian ini, kerajaan dan industri kemungkinan akan mempunyai
pemahaman yang lebih baik mengenai halangan-halangan yang dihadapi oleh IKS. Ini
xiii
membolehkan kerajaan dan syarikat untuk mengambil tindakan penambahbaikan untuk
mendorong dan pempromosikan inisiatif rantaian bekalan hijau disepanjang rantaian bekalan.

ABSTRACT
With the rapid growth and development of the industries, global warming and depletion of
natural resources have become a concern for the society, government and the industry.
Because of that, green topic has become an important issue. Although Penang government has
put heavy resources and efforts to promote and encourage green initiatives, green supply
chain has not been widely adopted by the industries in Penang especially SMEs. Thus, the
purpose of this study is to investigate barriers that hinder SMEs in Penang from adopting
green supply chain initiatives. In addition, it also investigates the moderating effect of
business strategic orientation on the relationship between the barriers and green supply chain
initiatives. To attain its’ objectives, questionnaire approach is adopted in this study and a
sample of 92 respondents is collected through questionnaire method. SPSS statistical tool is
used to test the descriptive and regression statistics. The result shows that the adoption of
green supply chain initiatives by the SMEs in Penang is low. The reasons of low adoption of
green supply chain initiative (green purchasing) are resource barrier and attitudinal and
perception barrier. Technical barrier proves to be the factor that impedes the adoption of
design for environment by the SMEs in Penang. However, the study found no convincing
evidence to support the moderating effect of business strategic orientation on the relationship
between the barriers and green supply chain initiatives. With the results and findings in this
study, government and industry would have a better understanding of the barriers that faced
by the SMEs. That allows government as well as big corporation to take corrective actions to
drive and promote green supply chain initiatives across the entire supply chain.

CHAPTER 1
INTRODUCTION
1.0 Introduction
With the increasing awareness of the environmental issues among the consumers, businesses
and government, that relatively boosted up the demand of green products. Therefore,
organisations either government sectors or private sectors are required to implement the
strategies to reduce environmental impacts of their products and services (Lewis & Gretsakis,
2001; Sarkis, 1995; Sarkis & Cordeiro, 2001). According to Hansmann and Claudia (2001),
success in addressing environmental items may provide new opportunities for competitions
and new ways to add value to core business programs. Therefore, market leaders in various
industries have taken a step ahead to green their internal operations through ISO 14000
certification.
According to Handfield (2005), the ISO 14000 principle provides framework which
guiding organisations to implement EMS that improves the environment performance. But,
the framework is only within the organisation’s operation boundaries instead of through the
supply chain. Other than that, Beamon (1999) said that manufacturing firms must follow the
basic principles established by ISO 14000 to extend to their suppliers in order to achieve the
green supply chain principle. Therefore, by getting its own internal operation to be certified in
ISO 14000 is only the first step for the respective organisation to participate in green
initiatives. However, it does not ensure that the whole supply chain is participating in green
supply chain initiatives. As a result, ISO 14000 is only limited to the implementation of EMS
within the organisation’s internal operation and it does not expand to the whole supply chain
of the organisation. Who should take the responsibility and initiative to ensure that the whole
2
industry is practicing green initiatives to reduce environmental impact? Is that the market
leader, government, industry or consumers’ responsibility? Therefore, to green the whole
supply chain is depend on the initiative of the organisation to either enforce the whole supply
chain to be certified in ISO 14000 or the organisation itself to drive and guide their own
suppliers towards the adoption of green supply chain initiatives. It is not an easy task to drive
the whole supply chain to be certified in ISO 14000 especially small organisations which have
limited resources. Hence, this study will look into the barriers that affecting SMEs to
participate in green supply chain initiatives in the local context.
1.1 Background of Study
As the global climate has changed rapidly due to the global warming, manufacturing and
production processes are viewed as the culprits in harming the environment, in the form of
waste generation, ecosystem disruption and depletion of natural resources (Fiksel, 1996). It is
necessary for the industry to react and transform the way of production systems operate
towards sustainability. It can be achieved by extending the structure from one way to a closed
loop supply chain, including supply chain operation designed for end of life products and
packaging recovery, collection, and reused in the form of recycling and remanufacturing
(Beamon, 1999).
Companies do not often change their businesses processes and this attitude allows
inefficient processes to continue unabated causing unnecessary waste and pollutions. For
example, ineffective processes in the US automotive industry allowed the innovative Japanese
automakers to become market leaders. Businesses that want to transform to a green supply
chain should take the opportunity to review all their business processes. It is to identify areas
where adopting a greener outlook can actually improve their business. Organisations should
3
review each process along the supply chain to identify if a more environmentally sound
approach will help to cure the inefficiencies that occurred.
Many companies in developed countries that have been gone through this exercise and
have identified the processes where raw materials were wasted; resources underutilized and
unnecessary energy used due to inefficient equipments. But according to Eltayeb and Zailani
(2009), there are still a lot of companies in Malaysia are still behind and yet to adopt the green
supply chain concept in their business strategy. Apart from that, Malaysian fully owned
organisations have the lowest level participation of green supply chain initiatives compared to
foreign based companies. One of the reasons that Malaysian owned organisations are having
the lowest participation of green supply chain as the green purchasing is still a very new
concept in Malaysia. Other than that, Lee (2008) found that a firm size is also an influence
factor for organisation to practice green supply chain, bigger size organisation tend to be more
willing to participate in green supply chain initiatives. According to Lee (2008), SMEs
usually lack of the information resources or expertise to deal with environmental issues.
Therefore SMEs can be a source of environmental risk and bottleneck in pursuing the goal of
greener supply chain.
1.2 Problem Statement
With increased pressures for environmental sustainability, it is expected that the
organisation will need to implement strategies to reduce the environmental impacts of their
products and services (Lewis & Gretsakis, 2001; Sarkis, 1995; Sarkis & Cordeiro, 2001).
Otherwise, organisation will loose its competitiveness in the market. Environmental impacts
occurred at all stages of a product production processes and supply chain. Therefore, in order
to reduce environmental impacts of a product, organisations have to ensure their own
4
production process and supply chain is practicing green initiatives. According to Rao and Holt
(2005), greening supply chain not only allow organisations to achieve substantial cost saving,
it would also enhance sales, market shares, exploit new market opportunities and stay
competitive in the market which lead to greater profit margins. All these benefits contribute to
economic performance of the organisation and also create job opportunities to the market
which help the economic growth of the country. Although adopting green supply chain
initiatives would allow organisation to enjoy all these benefits and contribute to economic
performance of the organisation. But there are still a lot of organisations in Malaysia still have
low involvement in the green initiatives. Under the pressure of global economy crisis,
organisations are struggling to fight for survival. Obviously, the main focus for organisations
is to be profitable and sustainable in the competitive market instead of green initiatives.
Therefore, cost reduction program has become a key agenda especially for SMEs rather than
green initiatives.
According to Eltayeb and Zailani (2009), local organisations in Malaysia have very
low involvement in green initiatives compare to MNC (Multinational Company). Other than
that, according to Wycherley (1999), small organisations have difficulty to drive its supplier
or suppliers’ supplier to involve in the green initiatives. Beside that, SMEs have difficulties in
obtaining financial and technological resources with the purpose of tackling their business
activities. Walker, Sisto and McBain (2008) identified various types of barriers which hinder
the adoption of green supply chain. The barriers included costs, lack of legitimacy, regulations,
poor supplier commitments and industry specific barriers. According to Lee (2009), adopting
green management into daily business operations require more innovative approach to
develop technological and organisational capabilities. Other than that, Wang and Ahmed
(2009) found that organisations that in family business with strong family orientation tend to
5
be more reluctance to accept changes and adopt new initiatives. Therefore, organisations that
under family business may have lower adoption in green supply chain initiatives. In addition,
green management activities required a large amount of resources in a diverse nature. That
showed that small organisations are facing various difficulties and barriers to adopt green
supply chain initiatives.
According to Penang government official website (www.penang.gov.my), Penang
generates about 1500 to 1600 tons of solid waste per day. MPPP and MPSP have spent
RM57.6 million in solid waste management. Therefore, Penang government decided to make
a big step that declared every Monday a “No Plastic Day” to all retail stores for Penang from
1st July 2009, and then further extended the “No Plastic Day” initiative to Tuesday and
Wednesday from 1st January 2010. That shows that government has made the move to reduce
the impact to the environment by reducing solid waste from the public. Based on the statistics
from Malaysia’s Productivity report 2008, SMEs contributed RM100,299 million or 30.9% of
total manufacturing output in year 2008. Therefore the success of SMEs is critical to
economic growth of Malaysia in the future. With the increasing trend of global environmental
protection awareness, SMEs in Malaysia will be out of the competition if green initiatives still
not adopted as part of their business strategy. As some trading companies managed to import
variety of items and things from other countries which the price is cheaper compare to our
local made products. Apparently, this actually creates a suffocating environment for our local
made products. Hence, SMEs must improve their competitiveness in order to compete in the
competitive market. Other than that, there is not much green supply chain literature in
Malaysian context available. Therefore, this study will focus on the barriers which impede
SMEs in local context to adopt green supply chain initiatives.

1.3 Research Objectives
By referring to the problem statement as above, few research objectives are formulated:
1) To understand the barriers and the level of green supply chain initiatives
adoptions by the SMEs in Penang.
2) To examine the significant level of the barriers that impeding SMEs to
participate in green supply chain initiatives.
3) To analyze the moderating effect of business strategic orientation between the
barriers and level of green supply chain initiatives adoptions.
1.4 Research Question
This study will try to answer the following research questions in order to achieve the research
objective as above:
1) What are the barriers and the level of green supply chain initiatives adoption by the
SMEs in Penang?
2) What is the significant level of each barrier that affecting local SMEs not to
participate in green supply chain initiatives?
3) Does business strategic orientation moderate the relationship between the barriers
and level of adoptions in green supply chain initiatives?
1.5 Significant of Study
This study will explore the barriers that impeding SMEs in Penang to adopt green supply
chain initiatives. By understanding the reasons of SMEs are still par behind the level, it will
allow the local SMEs along the supply chain, the Penang government and federal government
to take further actions to improve and promote the awareness of green initiatives in the
7
industries. According to Eltayeb and Zailani (2009), local organisations in Malaysia have very
low involvement in green initiatives compare to MNC (Multinational Company). By
depending on the MNCs to drive the green supply chain initiatives on their suppliers would
not be sufficient and effective enough to paint the whole picture. Local SMEs should be
involved to take their part in the green supply chain initiatives in order to reduce
environmental impact of their products and services.
1.6 Scope of Study
Based on the statistics in year 2009 from SMEInfo (www.smeinfo.com.my), 36% of the
SMEs in Malaysia are manufacturing sector and most of the SMEs are in the upstream of the
supply chain of the MNCs. It is vital to explore and understand the barriers that faced by the
SMEs to green themselves as well as their supply chain. Due to some constrains and
limitations in data collection, this study will only look into the manufacturing sector in
Penang instead of all sectors in the whole Malaysia. The scope of this study will focus on the
relationship of internal barriers and the three supply chain initiatives. Other than that,
moderating effect in terms of business strategic orientation with regards to the level of
adoption of green supply chain initiatives in their organisation and supply chain is also
evaluated in this study.
1.7 Contributions of Study
By exploring and understanding the significant level of each barriers faced by the SMEs in
Penang, this study will serve as the literature for organisations to have better understanding on
the barriers faced by their suppliers to become green as well as green their downstream
suppliers along the supply chain. Therefore the big organisations such as MNC that intend to
8
adopt green supply chain initiatives will be able to react and employing strategic actions to
drive and promote green supply chain initiatives to their suppliers. Furthermore, this study
will also allow government to take further actions to review and restructure regulations and
policies which help to encourage SMEs to participate in green supply chain initiatives.
1.8 Definitions of Key Terms
The following are the key words and phrases used in this research with its definitions within
the context of this document.
i) Green Supply Chain – A set of endeavors or efforts undertaken by a firm to
minimize negative environment effects associated with the entire life cycle of
its products or services starting from design of product, acquisition of raw
materials, product use, up to the final disposal of the product. (Zsidisin &
Siferd, 2001)
ii) Design for Environment – Design of product minimizing a product’s
environmental impact during its whole life cycle from acquiring materials, to
manufacturing, use, and ultimately to its final disposal without compromising
other essential product criteria such as performance and cost. (Johansson,
2002).
iii) Green Purchasing - An environmentally conscious purchasing initiative that
tries to ensure that the purchased products or materials meets environmental
objectives set by the purchasing firm, such as reducing sources of waste,
promoting recycling, reuse, resource reduction, and substitution of materials
(Carter, Ellram & Ready, 1998; Min & Galle, 2001; Zsidisin & Siferd, 2001).
9
iv) Reverse Logistics - The return or take-back products and materials from the
point of consumption to the forward supply chain for the purpose of recycling,
reuse, remanufacture, repair, refurbishing, or safe disposal of the products and
materials (Carter & Ellram, 1998; Stock 1998).
v) Attitudinal and Perception Barrier – Negative attitude towards environmental
initiatives, resistance to change, disbelieve of the benefits of environmental
initiatives (Perron, 2005).
vi) Information Barrier – No clear information regarding environmental benefits
(Hemel & Cramer, 2002), unaware of the environmental legislation and the
requirements (Simpson, Taylor & Barker, 2004).
vii) Technical Barrier – Not able to find alternative technical solution due to lack of
technical knowledge (Hemel & Cramer, 2002).
viii) Resource Barrier – Lack of financial resources, human resources and time

CHAPTER 2
LITERATURE REVIEW
2.0 Introduction
This chapter contains the literature review on the dependent variables, independent variables
and moderating variables. Other than that, this chapter also discussed about the definition as
well as the statistics of SMEs in Penang. This chapter consists of the review of SME in
Malaysia and Penang, evolution of supply chain practice, green supply chain initiatives,
consumer perceptions towards green and benefits and barriers of green supply chain adoption.
2.1 SME in Malaysia
SME in Malaysia have been defined according to size, turnover and activity. An enterprise is
considered to be an SME based on annual sales turnover or number of full-time employees as
indicated in table 2.1 and table 2.2.

An enterprise that has less than five employees or annual sales turnover of less than
RM200,000 is categorized under micro size SME. As for small and medium size SME,
enterprise that in manufacturing, manufacturing related services and agro-based industries
should have 5 to 50 employees (small size), 51 to 150 employees (medium size) or annual
sale turnover between RM250 thousand and less than RM10 million (small size), RM10
million to RM25 million (medium size). On the other hand, an enterprise that in service,
primary agriculture and information and communication technology (ICT) has lower limit in
terms of number of employees and annual sales turnover.

According to the Malaysia’s Annual Productivity Report 2008, SMI (Small and
Medium Industries) constitute 99.2% of total business establishment in Malaysia. Therefore,
Malaysian government acknowledged the importance to develop the capabilities of SMEs
sectors in order to broaden the sources of economic growth. The development of SMEs was
13
reflected in the Ninth Malaysia Plan (9MP: 2006 – 2010) and the Industrial Master Plan
(IMP3: 2006 – 2020). In 2008, SMEs produced RM100,299 million or 30.9% of total
manufacturing output. Most of the SMEs were involved in food and beverages (32.2%),
chemicals and chemical products (17.2%), rubber and plastic products (10.1%), fabricated
metal products (6.4%), and basic metals products (6.1%).
According to Business Times on 30th
July 2009, Malaysia government has approved
9.5 billion investments in green energy. The investment from the global large solar cell
manufacturer such as First Solar from US and Q-Cells from Germany has attracted the SMEs
in Malaysia to get involved and become part of the supplier along the supply chain in green
energy.
2.1.1 SME in Penang
According to Bernama (http://webevents.bernama.com/bernama/v3/news.php?id=198959),
SMEs played an important role in Penang's economy since the 1970s when multinationals
(MNCs) like Intel and AMD established their operations in the state. SMEs had been
servicing MNCs in various capacities under the global supplier programme and services
suppliers programme. That showed that the role of SME is significant to the growth of
economy not only Penang but Malaysia as well.

2.2 Evolution of Supply Chain Practice
The concept of SCM (Supply Chain Management) has been increasingly discussed
among academician and researchers as well as practitioners since mid 1980-s (Houlihan, 1988,
Jones & Riley, 1985) and lately companies have also started to work accordingly to its
principles. However, SCM could be seen in multiple contexts as the specifications and
definitions about content and meaning of SCM vary widely. Harland (1996) strongly agreed
that there is little consistency in the use of the term of SCM and little evidence of clarity of its
meaning. Table 2.4 gives a brief overview of different understanding of SCM. In an attempt
to systematize definitions and understandings, Bechtel and Jayaram (1997) identified four
perspectives, which so far dominate in SCM literature. They are functional chain awareness,
15
logistics, and information and integration process. This is supported by Kathawala and Abdou
(2003) that SCM has been poorly defined and there is a high degree of variability in people’s
minds about what is meant.
In regards with functional chain awareness, SCM covers the flow of goods from
suppliers through manufacturers and distributors to the end users (Houlihan, 1988, Jones &
Riley, 1985 and Langley & Holcomb, 1992). Whereas from the logistics perspective, “SCM is
a technique that looks at all the links in the chain from raw material suppliers through various
level of manufacturing to warehousing and distribution to the final customer” (Turner, Taylor
& Hartley, 1994, p.52). Johannsson (1994, p.525) defined SCM from perspective information
in which he stated “SCM requires all participant of the supply chain to be properly informed.
With SCM the linkage and information flows between various members of the chain are
critical to overall performance”. Lastly, from the perspective integration process, SCM is
defined as “the integration of business processes across the supply chain” (Cooper, Lambert &
Pagh, 1997, p.2).

Figure 2.1 illustrated the flow of supply chain which raw materials are manufactured
into final products then delivered to customers via distributions, retails or both. According to
Beamon (1999), traditional supply chain primary focused on optimizing the procurement of
raw materials from suppliers and the distribution of products to consumers.

By combining various definitions discussed above, Brindley and Ritchie (2001),
define SCM as “the management of material, information and financial flows through a
network of organisations (i.e., suppliers, manufacturers, logistics providers, wholesalers
/distributors, retailers) that aims to produce and deliver products or services for the
consumers”. It includes the integration, coordination and collaboration of processes and
activities across different functions such as marketing, sales, production, product design,
procurement, logistics, finance, and information technology within the network of
organisation and within the chain organisations. Besides these definitions, table 2.5 provides
more definitions for SCM that synthesized from the literature.

From the summary of the definition of SCM as illustrated in table 2.5, green initiatives
were not in the picture of the supply chain management. That becomes a culprit in harming
the environment in terms of waste generation, ecosystem disruption and depletion of natural
resources (Fiksel, 1996). Therefore, there is a need to green the manufacturing system by
changing the way of production system operates in order to reduce the impact to environment
along the supply chain. The change of the traditional structure from one way supply chain to a
18
closed loop, including supply chain operations design for end of life product and packaging
recovery, collection and reuse as defined by Zhu and Sarkis (2004).
The ISO 14000 principle provides framework which guiding organisations to
implement EMS to improve environment performance only within the organisation’s
operation boundaries instead of throughout the supply chain (Bansal & Clelland, 2004;
Handfield, 2005). According to Beamon (1999), in order to adopt the green supply chain,
manufacturing organisations must follow the basic principles that established by ISO 14000
and further extended to the supply chain. Similarly, Zsidisin and Siferd (2001) described that
green supply chain is application of environmental management principles to the entire
customer order cycle. This including design, procurement, manufacturing, packaging,
logistics and distribution. According to Sarkis (2006), green supply chain emerged from
performing environmental management in the context of supply chains. Comparing the
definitions of Supply Chain Management and Green Supply Chain Management, it is clearly
shown that green supply chain involved not only integrating the manufacturing processes and
distribution to customers. It also covers from the very beginning stage when the product is
designed until the product is disposed. That shows that it requires a full integration and
collaboration of the players along the product life cycle. Hoek (1999) summarized the players,
activities and evaluation of greening efforts throughout the supply chain as shown in table 2.6.

It is clearly showed in the table 2.6 that green supply chain involves the participation
from every player along the supply chain. All of these players play an important role in
greening the supply chain. Based on the concept of green supply chain, there is a wide range
of various green supply chain initiatives which are practiced internationally. Eltayeb and
Zailani (2009) reviewed and summarized twenty one literatures on green supply chain
initiatives as shown in table 2.7.

Based on table 2.7, Eltayeb and Zailani (2009) concluded that the green supply chain
initiatives can be generally classified into three major components:
1) Eco-design or design for environment
2) Green purchasing
3) Reverse logistics
These three green supply chain initiatives were selected as dependent variable in this
study as Eltayeb and Zailani (2009) reviewed that these three green supply chain initiatives
are most appropriate in the Malaysian context. Hence, organisations are required to
incorporate these three elements into their corporate culture and formulating a strategy and
practices in order to allow organisation to be the driver and initiator in green supply chain.
Accordingly, the following sub sections will discuss further on each green supply chain
initiatives. Although the population frame of the study by Eltayeb and Zailani (2009) was not
focused on SME, the three green supply chain initiatives mentioned as above can still be
21
applied in this study as the SMEs in Penang under manufacturing sector are mostly the
supplier or the supplier’s supplier of the big organisations.
2.2.1 Design for Environment
Design for environment (DfE) is a concept which reduces the impact to damage the
environment of products or services across its life cycle. According to Lewis and Gretsakis
(2001), the environmental impact of any product or material is “locked” into the product
during the initial design stage when materials, processes are selected. Therefore design stage
is very important to determine if a product life cycle creates impact to the environment. The
impact of product life cycle is evaluated against various aspects, for example the alternative
options for reducing waste and energy, recycling or elimination of product waste during
manufacturing. Design for environment provides guidelines for the design engineer to
examine the environmental friendly and soundness of a product over its entire life cycle
(DeMondonca & Baxter, 2001). A comparison of the objectives between DFE and ISO 14000
by Demondoca and Baxter (2001) concluded that DFE is more comprehensive than ISO
14000. That also aligns with the finding from Bansal and Clelland (2004) and Handfield et al.
(2005) that ISO 14000 standard does not provide sufficient components to support green
supply chain approach. The difference can be clearly seen in the table 2.8 as below.

Hemel and Cramer (2002) summarized 10 most successful designs for environment
principles and practice as below. Enhancing design for environment in SMEs does not only
depend on finding solutions for technical problems, more important is economical factors and
social factors such as the acceptance of environmentally improved products in the market.
1) Recycling of materials
2) High reliability / durability
23
3) Low energy consumption
4) Remanufacturing / refurbishing
5) Less production waste
6) Clean production techniques
7) Reduction in weight
8) Clean materials
9) Less / clean / reusable packaging
10) Recycled materials
Other than minimizing environmental impacts, products that consuming less materials
or energy would definitely tend to be more profitable and competitive in the market. Thus,
design for environment is an important practice to reduce impacts to environment from their
products and manufacturing processes as well as a competitive advantage for an organisation
to compete in the market.
2.2.2 Green Purchasing
Green purchasing means that purchasing or supply chain managers consider the issue of
sustainability in their purchasing of inputs in addition to the traditional purchasing criteria of
cost, quality, and delivery (Lambert & Cooper, 2000). Hamner (2006) suggested seven basic
elements for green purchasing as below.
1) Product content requirements
2) Product content restrictions
3) Product content labeling or disclosure
4) Supplier questionnaires
5) Supplier EMSs
24
6) Supplier certification
7) Supplier compliance audit
By having all these elements in the SMEs’ organisation require additional effort and resources.
According to Lee (2008), buyer is the most important influential stakeholder for the
supplier to participate in green supply chain initiatives. That showed that green purchasing is
one of the key elements for organisations to participate in green supply chain initiatives.
However, Zsidisin and Hendrick (1998) concluded that purchasing managers are not the only
driver to promote and influence the environmental supply chain involvement, it is the top
management’s responsibility to prioritize the environmental concerns and cascade through the
entire organisation which involve procurement, logistics, warehousing practices, operations,
marketing, and governmental agencies. Therefore, the green purchasing initiatives can be
viewed in two perspectives which are internal and external. In terms of internal perspective,
top management is the key driver to drive its organisation to take part in green supply chain
initiatives by putting priority to drive all levels in the organisation. On the other hand, in
external perspective, purchasing managers are the driver to drive its supplier along the supply
chain to participate in green supply chain initiatives.
2.2.3 Reverse Logistics
According to Hanafi, Kara and Kaebernick (2008), reverse logistics consists of five main
activities which are collection, inspection, separation, reprocessing and distribution. It is
defined by Carter and Ellram (1998) as returning the end of life product or packaging from
end user back to the supplier. The supplier can recycle, remanufacture, repair, repackaging,
reclaim or safe disposal of the material as illustrated in figure 2.2 as below. Similarly, Stock
(1998) explained that reverse logistics can also involve product return, source reduction,
